Automated reconstruction of subsurface interfaces in Promethei Lingula near the Martian south pole by using SHARAD data
Subsurface layers are preserved in polar regions on Mars, which are considered to be a record of past climate changes on Mars. Orbital radar instruments like the SHAllow RADar (SHARAD) on board Mars Reconnaissance Orbiter (MRO) transmit radar signals to Mars and receive a set of signals returned fro...
